I have a list of discrete points wich I want to use as nodes for creating a 2D mesh. I used DelaunayMesh and it works fine. The problem that I have is that some elements/polygons are outside of the ...

As what is proving to be a difficult, but entertaining task, I am attempting to adapt a 2D meshing algorithm created for MATLAB and port it to Mathematica. I understand meshing functions already exist ...

I am trying to create a simple, almost transparent 3D sphere with a mesh that is made of solid lines if they are on the front surface (i.e. if they are directly visible) and of dashed lines if those ...

I honestly have no idea where to begin with this problem. In summary, I have a 2D coarse grid with an intersecting line. For an easy example, let's assume it's a 4x4 grid.
I wish to pass through each ...

I am new to Mathematica, and I am trying to create a 3D hexagonal mesh on a 3D surface. It is very similar to what was done in this post Create a torus with a hexagonal mesh for 3D-printing, but now ...

My question is inspired by this answer about meshing with quadrilateral elements.
The following functions are my (naive) try of implementing the Laplacian smoothing. I find interior nodes in the mesh ...

I would like to mesh the surface of a cloud of points that may not be completely convex, for example the points in this question.
Mathematica does not provide triangulation of 3D points, but there is ...

I need to resolve the diffusion equation in a domain with circular sources (holes).
I've tried defining the whole region with holes but the result is very mesh-dependent and not symmetric, so at the ...

I try to generate a mesh over a region, which has a wavy boundary at its bottom and needs very fine mesh around the bottom.
However, the generated mesh boundary is not as smooth as the specified one. ...

There are a lot of answers for how to make a hexagonal mesh on a 3D surface but nothing on how to make a hexagonal mesh on a 2D surface. Can any provide code on how to do so? I am new to mathematica, ...

I am new to Mathematica and I am currently in need of some help with creating a neighboring list of triangles for a given triangulation and finding the path to the triangle containing the random point ...

How to calculate a Delaunay mesh nerve? A Delaunay mesh nerve
is a collection of triangles that surround a single triangle called the nerve nucleus. The triangles in a Delaunay mesh nerve either have ...

This relates to a previous question I had about formulating an interpolation over an unstructured grid.
A new issue I am running into (in this test example) is that some of the coordinates that are ...

When I create a contour plot it looks fine. When I copy as PDF, and paste into another document (e.g. Apple Mail, Keynote, etc.) it has an extra unwanted white mesh. This occurs even when the option ...

I am looking to put a cool geometric mesh on this object. I came across this question that explained how to put a hexagonal mesh on a parametric equation but I have a series of geometric objects of ...
